ABSTRACT:
A two-stage dynamic classifier (30, 30′) for classifying a pulverized feed material (34, 34′, 38) entrained in an air flow (31) includes a vertically extending housing having a lower feed material inlet (18), an upper feed material outlet (24), a processing section (47, 47′) disposed between the feed material inlet and the feed material outlet, and a lower tailings discharge (26). A classifier conditioner (32) is disposed in a lower portion of the processing section and a turbine classifier (42, 44) is disposed in an upper portion of the processing section.
